History

With Brock

Kanto

Geodude fighting Pidgeotto

Geodude was first seen in Brock's rematch with Ash at the Pewter City Gym. It was used against Pidgeotto where it was shown to have a powerful defense, not even being fazed by Pidgeotto's Gust, and managed to defeat it without any trouble. It was then used against Pikachu but was fried by a very powerful Thunderbolt, despite the fact that it is immune to Electric moves.

Similar to most of Brock's Pokémon, Geodude received very little screentime. Brock typically used it in situations in which he needed to battle, but could not use Onix because of its enormous size. One such occasion was Battle Aboard the St. Anne, when it joined a large group of Geodude to attack Team Rocket.

Brock entered Geodude in the P1 Grand Prix in The Punchy Pokémon. It lost in the first round to Giant's Hitmonlee which was used by Team Rocket. Initially, Brock sent Geodude back into the ring where it was kicked mercilessly, but on Anthony's advice, Brock threw in the towel and apologised to Geodude for making it fight.

Johto

Misty polishing Geodude

It returned with its Trainer and fellow Pokémon in A Tents Situation. In Sick Daze, it was revealed that Brock usually polished his Rock Pokémon, so Misty took up the job of polishing Geodude whilst Brock was sick. It was captured by Team Rocket, but was rescued when Brock, Pineco and Golbat intervened.

In Control Freak!, Geodude dug a pathway to get into the ancient ruins. However, once inside, Jessie, in possession of the ancient Queen's mask and scepter, took control of Geodude, along with Onix and Pikachu. However, once Jessie, James and Meowth escaped with Pikachu on Onix, Geodude was left behind and snapped free of Jessie's control.

Geodude was revealed to know Mega Punch in EP250 (an unaired episode in the dub) where it fought Jessie's Arbok, but was easily defeated with Headbutt and Wrap. It was then stolen by Team Rocket, but recovered later. It acted as a fire fighter for the third time in Great Bowls of Fire!, where it attempted to rescue the Pokémon trapped in a fire. It managed to save the sacred Prayer Flame from the burning shrine at the end of the episode. In Entei At Your Own Risk!, Geodude was sent out to enjoy the hot sands. It pushed Ash's Larvitar headfirst into the hot sand, having no patience for its timidity.

Personality and characteristics

Geodude received very little character development as it did not receive much screen time. However, it comes across as one of the older Pokémon in the show, with quite little patience for wasting time. This was shown by the fact that it shoved Larvitar into the sand headfirst, during Entei at Your Own Risk having no patience for babying it like Ash, Pikachu and others. It is very fond of its Trainer, who had trained it for many years, and was known to polish Geodude for maintenance.

Brock used his two Geodude in his battle against Ash in Play Misty For Me, where they lost. They later fought a losing battle with the Black Fog.

Trivia

Geodude is the only Generation I Pokémon Brock still owns that hasn't evolved yet, despite its game counterpart presumably being shown as a Graveler in Generation II, and eventually a Golem by the rematch in HGSS. His Zubat and Onix already evolved to their final forms, and Vulpix is owned by a different Trainer: Suzy.

Geodude is the only one of Brock's Pokémon which has not had the circumstances of its capture shown in the anime.

Geodude was not shown using any moves until 20 episodes after its debut.
